TCP session: Circle of Life
In my last video, I demonstrated how to display active TCP/UDP connections on my Windows. Today I will talk about TCP connection states. TCP is Transmission Control Protocol. It is the most popular transport protocol on a TCP/IP network. TCP is a connection-oriented and reliable protocol.
When TCP is used to transmit data, it will include three stages: session starting; data transmission; and session termination/closing.
A state indicates a specific connection status during/in each step of the session process. The possible states include LISTEN, ESTABLISHED, CLOSE_WAIT, CLOSED, and some others. I will use the TCP session process to show different connection states both from a client and a server.
